When selecting a model, please note that the measured medium should be compatible with the part of the product that is in contact with the medium.Cable wires are available in Nitrile and Polyethylene. Nitrile has good versatility, oil resistance and wear resistance; polyethylene has good toughness and excellent electrical insulation and stability. Unless otherwise specified, it is shipped as a nitrile cable.The standard cable length is 1.5 meters.

Hydrostatic Pressure Sensor to Measure the Liquid Level

Pressure transmitters are currently widely used in papermaking, steel, chemical, sewage treatment, heat, electricity, tap water, food and other industries. In addition to measuring the pressure of the medium, the pressure transmitter can also be used for other purposes, such as using the gravity of the liquid to measure the liquid level.

Hydrostatic Pressure Sensor is used to measure the pressure of pipeline or tank medium. It can also be used to measure liquid level.

Please note that the Hydrostatic Pressure Sensor can measure the liquid level of open containers. Airtight pressurized containers will not work.

Hydrostatic Pressure Sensor to Measure the Liquid Level​ 1

As shown above.
The first is to mount the SI-126 Hydrostatic Pressure Sensor above the tank. Make sure the sensor is 15cm above the liquid level.
The second is to install the SI-126 Hydrostatic Pressure Sensor at the bottom of the tank. Install the upper needle shut-off valve.

Hydrostatic Pressure Sensor Liquid Level Measurement Principle

Measuring principle with Hydrostatic pressure:

In a static liquid: The static pressure at a point in the liquid is proportional to the distance from that point to the liquid surface. Namely: P=ρgh.

in,
P-the pressure (pressure) of the measured point,
ρ-medium density,
g-acceleration of gravity,
h – the height from the measured point to the liquid surface.
